Firstly
Yes that PC can handle DDR4 3200mhz and the 3080 should be able to run without issues
Games:
Diablo 4: should be able to run without issues at 1080p 60+ FPS and more.
RDR2: Yes, with the hardware in the pc you should atleast get 60+ FPS on 1080p and without issues.
Building a PC aint that hard, but if you never done it i recommend you to check youtube and be careful not to break anything!
